4. To Catch a Killer

Brian Dennehy won an Emmy for his amazing performance in 1992’s To Catch a Killer—a TV movie based on the life and crimes of serial killer John Wayne Gacy. After a string of rapes and murders in the 1970s, Gacy was caught when police discovered dozens of victims buried in the crawl space of his home and on his property. He was nicknamed the “Killer Clown,” as he used to dress up in costume for charitable events and children’s parties (shudder). His character was named “Pogo”—and seeing Dennehy in Gacy’s full garb is absolutely chilling.
